Change subject: IMPALA-8704: ISO:SQL:2016 datetime patterns - Milestone 2 ...................................................................... IMPALA-8704: ISO:SQL:2016 datetime patterns - Milestone 2 This patch adds additional datetime format tokens on top of what was introduced with Milestone 1 (IMPALA-8703). The tokens introduced: - Free text token: Surrounded by double quotes, a free text section can be given in the format where the same text is expected in the input without the surrounding double quotes. - FX modifier: This modifier has to be given at the beginning of the format and is valid for the whole format. In a string to datetime conversion this forces strict separator matching and expects all the tokens in the input to have the same length as their maximum length. E.g. A month has to be of length 2 prefixed by zero if needed. This is the default in a datetime to string conversion. - FM modifier: This modifier affects only the following token and overrides the FX modifier. Using this the value of a token can be shorter than the max length if followed by a separator. E.g. 1-digit month, less than 4-digit year, etc. This is the default behaviour in a string to datetime conversion.
